The operating system for Apple computers is fraught with many useful “chips”. Only some of them are reported in press releases, while the rest are gradually found by users on their own. In this article, we will talk about a rather trivial function – volume control. Even in this simple action, the developers from Cupertino were able to add something useful.

Apple keyboards for personal computers and built-in keyboards in MacBook have dedicated volume buttons (F10, F11, F12). when you click on them, a toast notification appears with a volume bar, similar to the notification in iOS. Keyboards from other manufacturers usually have volume buttons as well.
There are 16 divisions in total on this scale. But what if you need to adjust the volume more precisely? For this, key combinations are provided ⇧Shift + ⌥Alt (Option) + F11 and ⇧Shift + ⌥Alt (Option) + F12…

When using these combinations, each division will be divided into 4 more points, as in the screenshot below.
The same will happen if you use similar keyboard shortcuts to adjust the brightness of the screen, but instead of F11 and F12, you need to use F1 and F2, respectively:
⇧Shift + ⌥Alt (Option) + F1 and ⇧Shift + ⌥Alt (Option) + F2

How to adjust sound quietly on Mac (no extra signature sound effect)
When adjusting the volume, the computer emits a characteristic sound, which in some situations may be very unsuitable. To do this, you can use the following keyboard shortcuts: ⇧Shift + F11 and ⇧Shift + F12… You can completely disable this sound effect in the system settings. To do this, you need to open the application System settings go to section Sound → tab Sound effects and disable the option “Beep when volume changes “…
MacOS also assigns different volume levels for built-in speakers and connected headphones / speakers. If you adjust the volume in the laptop to minimum, then plug in the headphones and accidentally unplug them, then the MacBook will not scream with the built-in speakers, since the volume will return to the minimum value.
The volume level can be adjusted even from the Terminal, for this use the following command:
osascript -e "set volume х"
Instead x put value off 0 before 7… This command can be used in conjunction with Automator to fine tune your system.
